This application is a National Stage completion of PCT/SE2007/000550filed Jun. 8, 2007, which claims priority from Swedish patentapplication serial no. 0602072-1 filed Oct. 4, 2006.

FIELD OF THE INVENTION

The present invention relates to an installation unit in an energydistribution system—for a heating or cooling system—a number offunctions or products having been integrated into an installation andservice unit, which allows completely new conditions for theinstallation work as well as for the maintenance jobs in the system.

BACKGROUND OF THE INVENTION

In the installations, which exist today, for a heating or coolingsystem, a number of components or functions are integrated, whichjointly provide a system for distributing the energy distribution out tothe various apparatuses or premises, which exist in the particular case.

In these systems there is e.g. an integration of components forcontrolling the temperature regulating valves and/or thermostatvalves—often provided with some type of adjustment devices—as well as anumber of additional functions, e.g. connection points for filling ordischarge of the system, for flushing, for dirt collection, for adeaeration device, for flow regulation, for various types of reading ofe.g. volume flow or energy as well as various types of supervision.These various functions and components respectively often are mountedadjacent or directly connected to the heating or cooling assemblies;i.e. valves etc. are often mounted directly connected to a radiator or acooling battery, a connector, namely out in the various rooms/premises.

In modern systems some of the above-mentioned functions are used, butthe installation engineering or rather the systems available for theconstruction of the complete distribution system has a few drawbacks,which the present invention seeks to eliminate.

The worst drawback of the modern systems is the fact, that they havebeen developed from simple systems, in which a smaller number ofcomponents or functions were jointly integrated.

However, in modern complicated systems, not only regarding the energycomponents but regarding the entire construction process, there has beena continued modifications of the systems already constructed, anoptimization of the costs for the various integrated components oftenbeing done, without considering the entirety of the whole system, theentirety today being influenced by many different jointly responsibleparticipants.

With regard to the modern systems, there is often a conflict betweenvarious participants in connection with the construction process. Thevarious working moments will, using the modern systems, be completelydependent on each other. Also, in other phases of the installationprocess often different interests collide.

As an example it can be stated, that adjustment of an energydistribution system often is done, when the already are being used andwhen the particular premises are not available in the same way as in anearlier phase of the construction process. Also, in other situationsconsiderable problems regarding the accessibility arise, when aconstruction must be adjusted or some components must be exchanged orthe like.

The energy distribution systems have so far been constructed with asuboptimization as an initial position. This suboptimization means, thatthe systems will comprise a number of components, which per se,considered separately, are cost efficient, but that the total cost ofthe system “in situ” or for its maintenance has not been consideredthoroughly, when the constructions have been developed.

Not only the cost of the installation but much more the cost and thefunctionality during the technical life of the system consequently isthe basic theory behind the present invention. Thanks to the presentinvention entirely new conditions have been obtained for themanufacture, the installation and the maintenance of an energydistribution system, which conditions allow completely new possibilitiesduring the various phases of the construction and the useful life of abuilding.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 shows an example of how a complete installation unit 1 accordingto the present invention is constructed; and FIG. 2 shows an embodimentof an installation unit without a cabinet 7.

These figures show a design, which only is one example of how integratedcomponent parts are assembled. Thus, within the scope of the inventiveidea, a complete installation unit 1 may be provided with additionalcomponents, which may be directly or indirectly mounted on distributors3 or alternatively constitute e.g. complementary parts to the functionalcomponent. Functional component 5 may e.g. represent electricaladjustment means, instead of the manual ones, shown in the figures, aswell as mounted transmitters for remote reading and remote controlrespectively of the mounted valves: Also, as examples pressure andtemperature transmitters may be mounted in the various measuring nipples12, 13, 17 and 67, which consequently allow a direct or indirectreading.

According to a preferred embodiment of the invention the variouscomponents are mounted in a cabinet to obtain a complete installationunit 1, which results in, that the installation—the installation work aswell as the component placements—will be completely changed compared tothe installation principles used today, resulting in the advantages,which the present invention allows.

The primary piping system is connected to the unit—intake 8 and return 9respectively—connection tubes at 8 and 9 respectively comprisingconnection ends 10, which optionally are threaded, provided with flangesor are flat, as is shown in FIG. 1.

At connection 8—on the intake side of the unit—a balancing valve 11,with its measuring nipples 12 and 13 respectively, is mounted as a firstcomponent.

Balancing valve 11 advantageously has an internal thread at its twoends. The balancing valve 11 is connected to a distributor 3 by means ofa connection piece 14.

The connection piece has an external thread, directed towards balancingvalve 11, and a bayonet connection at the end, which is connected todistributor 3.

The construction of the bayonet connection is shown in FIGS. 3A-3G.Also, the separate distributors 3 are connected in an axial directionusing the same principle and normally 2-4 distributors are connected inseries. The last distributor is normally terminated with a connectionpiece 15, which is terminated with a plug 18, which also is mounted viaa bayonet holder in connection piece 15.

At connection 9—on the return side of complete installation unit 1—adifferential pressure valve 16 with its measuring nipple 17 is mountedas the last component.

Differential pressure valve 16 preferably is threaded in its interior atits two ends and is connected to distributor 3 by means of a connectionpiece 14 in the same way as balancing valve 11. As the last component onreturn side 9 there is a connection piece 15, which advantageously maybe similar to the one, which is mounted on the intake side. As analternative to plug 18 this connection piece may be provided with acoupling 19, in which in a particular case e.g. a discharge or adeaeration function is mounted.

Distributors 3 and connection pieces 14, 15 are mounted in a profile 4,which is described in more detail below.

In order to be able to always carry out a simple installation or serviceof the complete system complete installation unit 1 is constructed insuch a way, that complete cabinet 7 comprises a number of sides/parts,which, when assembled, constitute the complete cabinet. The completecabinet preferably is made of a sheet metal material or alternatively asuitable plastic material.

In order to carry out the installation work in a simple fashion and witha satisfactory accessibility to all the components cabinet 7 willcomprise a back plate 20 and a bottom plate 21, which advantageously arebent in one piece. On this work piece—20/21—profile 4 is fastened bymeans of screws or the like. Subsequently the valves, distributors,functional components and connection pieces, which will be used in theparticular construction, will be mounted.

When the pipe work/installation has been completed, lateral pieces 22and 23 and lid 24 respectively will be mounted. Lateral piece 23preferably is slit, allowing it to be pushed inwards above connections 8and 9, whereas lid 24 preferably consists of two portions in order toalso allow a dismounting, after the connection of tubes 25 to theinteracting tubes from e.g. radiators or convectors, which completeinstallation unit 1 interacts with. As the last step lid 24 is screwedor in another way fastened to sides 22 and 23 and the sides of bottomplate 21 respectively.

The distribution of the total flow outwards to the various consumptionunits, e.g. convectors, is done via stop valves 29, mounted in cut-offs30 on distributors 3. Stop valve 29 has a pipe coupling 31, to which atubular loop 32 is connected and the return from this tubular loop 33 isconnected to return connection 34 by means of its pipe coupling 35 tofunctional component 5.

The entire installation unit 1 is mounted and function tested, e.g.tested regarding pressure, in a factory, which allows a high degree offunctional reliability.

A possible leakage in installation unit 1 can be easily indicated, sincethe unit is mounted in a cabinet 11, and this means, that the risk ofwater damage to the building is minimized.

The integration of several functions in an installation unit 1 accordingto the present invention results in several advantages.

Thus, several functions have been assembled in just one place andconsequently been removed from earlier locations, in which they havebeen scattered and e.g. mounted in various places and often connected toother components in the system. Thanks to the present invention aheating and cooling plant can be constructed in such a way, that theinstallation contractor mounts e.g. radiators in the building at onemoment and in a later stage interconnects the same to obtaininstallation unit 1. Also, the contractor can make his tubing from theheating or cooling assemblies up to the installation unit 1 at the sameoccasion and at a later occasion make the final interconnections of thevarious heating and cooling assemblies to the primary energy source orto tubing system originating from the same. It is also possible toconnect e.g. one portion of the building to the complete heating orcooling system without the need at this time to connect all otherportions of the building. This means, that installation unit 1 in afirst phase comprises several distributors 3, one or several of thembeing provided with plugs in connections 30. In a second installationstep additional functional components 5 can be interconnected, if theyare required. Even if from a structural engineering point of view itwould not be advantageous to mount the installation unit in a cabinet 7,this design is nevertheless an embodiment of how the present inventioncan be used—see FIG. 2.

The installation unit replaces the demand for externally, e.g. in eachpremise, mounted valves, designed to control the flow and then also theroom temperature. By using functional components 5 and stop valves 29and additional components, e.g. filters and stop valves, which may bespecific for the installation, has in this way all the installation andpreliminary adjustment work regarding the components, which normallyconstitute parts of normal cooling and heating installations, i.e.primarily flow regulating valves, stop valves, discharge valves andfilters, been removed from the various premises, and instead been unitedin just one place, the installation unit.

The installation unit can be mounted in an optional place, e.g. in apassage or in an appliance room. The separate locations, with theirconvectors or heating elements, which are connected to the unit,consequently will be freed from all kinds of installation work, as soonas the intake and return ducts have been mounted between the devices andthe installation unit. The interconnection of the ducts with theinstallation unit can be done in a later phase. This means, that thevarious premises do not have to be accessible in a later phase, whene.g. the final adjustment work will be done or a change will take placeregarding the choice of components or the service of the components.This is a great advantage in comparison with the presently used systems,in which this accessibility always is a requirement.

By using installation unit 1 according to the present invention aconcentrated localization of the functional components can be attainedand then also a number of advantages, as follows:

-   -   Installation unit 1 allows an accessibility to this unit and        consequently also to the interconnected components.    -   All the service work can be carried out in just on place.    -   The interconnection of installation unit 1 to primary piping        system 6 can be done at one specific time and not necessarily        connected at the time, when the separate premises are prepared        or are interconnected to the distribution unit.    -   The interconnection and the connection of the separate        rooms/premises can be done successively to the installation        unit.    -   Installation unit 1 can be developed with additional        distributors 3, in case e.g. new premises or other room        divisions must be connected in a later phase, without affecting        already connected premises.    -   Supplementary uses of/exchanges of functional components can be        done in a later phase.    -   Measurement and supervision of the energy status of the various        premises can be done through the installation unit.    -   Using a complete installation unit 1 reduces the risk of water        damage in the building.    -   By using an installation unit, which is prefabricated, a        controlled, functionally reliable product is obtained.

The various portions of installation unit 1 are described in detail inthe following figures.

FIG. 2 shows installation unit 2, which comprises all the tubular andfunctional components, which are integral parts of complete installationunit 1, including profile 4, without a surrounding cabinet 7, and in aview, seen from the rear portion of the installation unit in relation tointake 8 and valve 9. As the last component connection piece 15 ismounted. In order to obtain an axial mounting position for theconnection piece and consequently also other parts, connected in series,connection piece 15 is provided with a flange 26. This flange has adiameter, which is proportional to profile 4 in such a way, that flange26 bears against end gable 27 of the profile. With this fixed positionof the connection piece and of the distributors certain positions forall the tube cut-offs are obtained, which originate from thedistributors and consequently the position for the tubes 32 and 33 inrelation to profile 4 is given. There is no absolute retention ofconnection piece 15 or distributors 3 in the opposite axial direction,but lid 24 and its pipe passthroughs 28 constitute there a support likethe final connection of inlet 8 and return 9.

FIGS. 3A-3G shows the principal construction of distributor 3.

Normally the distributors are made with 2 pieces of cut-offs 30, but thenumber of the cut-offs varies preferably between 1 and 4 pieces. Inthese cut-offs functional components 5 are mounted, which may have anumber of different functions or combinations of functions. In thedescription—see FIGS. 4, 4A—a preferred design of the interconnection ofthe functional component and the distributors has been described, butthis design is just one example within the scope of the invention. Thedesign of the connections ends of the distributors is shown in FIGS. 3A,3C, 3D, 3E.

These figures shows, that the distributor has a female part 36 and amale part 37. These two parts are joined and then O-ring 38 in thefemale part will glide upwards on cylindrical part 39 of the male part.The female part has an inner diameter 41 with an O-ring groove 40 and ashort cylindrical part 42 outside the O-ring groove, with the samediameter as 41. The female part is terminated with two shoulders 44,positioned in a diametrical direction in relation to each other andwhich each extend preferably somewhat less than 90° around the peripheryof the female part. The shoulders have an inner diameter, which issomewhat larger—preferably 1-4 mm—than inner diameter 41 of the femalepart and an axial extension, which preferably is 2-4 mm.

Male part 37 is designed in such a way, that outer diameter 39 with itsfront oblique surface 45 cooperates with inner diameter 41 of the femalepart and with O-ring 38 and at the same time as male part 37 has twocylindrical portions 46, which after the interconnection of thedistributors engage groove 43 of the female part and consequently lockthe distributors in an axial direction. Cylindrical portions 46 arelocated at the same distance from flange 47 of the distributor, whichconstitutes the end of the male part inwards towards the distributor,like the thickness of shoulders 44, and has a thickness, which isadjusted to and which cooperates with groove 43 and its width. In aradial direction the length of cylindrical portions 46 are coordinatedto enable them to be inserted between the two shoulders 44 of femalepart 36 and the distance, which exists between these shoulders.

FIGS. 3B, 3F, 3G show, how distributors 3 are interconnected. In theupper figure the male and the female parts have been pushed into eachother, cylindrical part 39 of the male part being integrated with O-ring38 of the female part and with inner diameter 41 of the female part.However, in the upper figure the right distributor has not been turnedyet in relation to the connection of the interconnecting distributor,which means, that in this position shoulders 44 of the female part havenot engaged the projecting cylindrical portions 46 of the male part.FIG. 3F the right distributor has been turned 90°. In this position thecooperating connection ends—the male and the female parts—have occupiedtheir final positions and this means, that the two distributors aremutually locked in an axial direction. In this position all cut-offs 30are parallel and directed in the same direction. In connection with thesubsequent mounting of the distributors in profile 4 also their mutualposition in a rotational direction will be locked. The locking is done,because locks 65, which are located on the periphery of the distributorand which are located with a 90° division and where a spring extendsthrough the center for cut-offs 30 and the rest thus with a 90°displacement to this plane, engage with corresponding groove 64 inprofile 4. The length, height and width of the springs have beenevaluated. The length is practically about the same as the distributorexcluding its connection ends, whereas the width or thickness is about2-6 mm and the height preferably is about 5-30 mm. The springspreferably are provided with recesses 77, which make them less expensiveto manufacture and which of course can vary as to shape and numberwithin the scope of the invention. The distributor can of course bedesigned with only 2 or 3 springs, but 4 springs result in castingtechnology advantages, since a more even material distribution in theblank to the distributor is obtained. Consequently shrinkages duringcasting can be avoided. The mounting of the distributor in the profileis described thoroughly, reference being made to FIG. 5.

FIGS. 4, 4A show, how the various functional components 5 are mounted ondistributor 3. Cut-offs 30 of the distributors are designed in such away, that a functional component 5 and its connection end 55 can bepushed into cut-off 30 and be fixed by means of a locking ring 48. Inmore detail cut-off 30 is designed with a turned interior surface 49,which cooperates with a guide pin 50 on connection end 55, the guide pinhaving a diameter, which cooperates with surface 49 in order to give thefunctional component a guided, stabilized fastening in distributor 3.Outside surface 49—at a larger distance from the center of thedistributor—there is a second interior turned surface 51 and thissurface cooperates with second cylindrical part 52 on the functionalcomponent, which has a somewhat, preferably 2-5 mm, larger diameter thanguider pin 50. The length of these two turned parts 50 and 52respectively preferably is 10-20 mm. On the cylindrical part 52 there isalso an O-ring groove 53 with a mounted O-ring 54.

In order to be able to fix functional component 5 to distributor 3connection end 55 is provided with a resilient, open/slit locking ring48, mounted in a groove 56, which is located on cylindrical part 57,which has a diameter, which is a few additional mm longer than theadjacent cylindrical surface 52. Cylindrical part 57 locks the positionof locking ring 48 in an axial direction and this locked position isalso secured by flange part 58, which constitutes the transition fromconnection end 55 of the functional component to that part, whichcontains the functional part itself.

On cut-off 30 of the distributor there is a cylindrical interior surface59, immediately outside surface 51, with a turned groove 60, which has awidth and a depth, which are chosen in order to be able to cooperatewith locking ring 48 and cylindrical part 57 of connection end 55.

When connection end 55 is pushed into cut-off 30, the two open endportions 61 of locking ring 48 are pressed together and are notreleased, until the connection end has entered into its final position.Then the legs of the locking ring spring outwards and into groove 60 andlocks the connection in an axial direction.

The functional component can always be dismounted, since it is then onlynecessary to press the two end portions together or the legs on lockingring 48 and subsequently it is easy to draw out connection 55 fromcut-off 30.

In order to control the functional component—prevent it fromrotating—cut-off 30 is provided with two diametrically opposedprojecting portions 62. These portions 62 have an inner diameter, whichis somewhat larger than the outer diameter of the cooperating recess 63in connection end 55. When functional component 5 is pushed into thedistributor, projecting portions 62 climb on or pass surface 63 onconnection end 55. The periphery and the projecting length of portions62 is coordinated with corresponding recess 63 in flange portion 58 ofconnection end 55.

FIG. 5 shows, how a distributor 3 is mounted in profile 4.

Profile 4 preferably is an extruded Al-profile and its main task it torotationally fix the distributor. According to the present invention theprofile is designed to be able to fix two rows of distributors, whichmeans, that one row with e.g. three integrated distributors are placedin one row, whereas the corresponding three distributors are mounted ina second row.

The distributors are fixed in a rotational direction, since profile 4 isprovided with circular segments 73 and 74 respectively with three andtwo respective grooves 64, which have a width and a depth, which arecoordinated with the thickness and the radial extension of springs 65 ondistributors 3. Distributors 4 preferably have springs, one springpassing through the center of cut-off 30. These springs may within thescope of the present invention have various lengths and shapes, but thefunction to control the position of the distributors in relation toprofile 4 as well as to obtain an improved symmetry regarding themanufacture/casting of the distributors is the main function.

The distance between the two distributor rows in profile 4, from thecenter of the distributors, is to be chosen in such a way, that it willbe easy to obtain a simple joining of the various components, which willbe mounted in a certain installation situation. Thus, a distance ischosen in a height direction as well as in another direction, whichmeans, that components can be mounted and service be carried out and ata minimal cost. One example of a distance between the two rows is, that“a=80 mm” and “b=40 mm”. The “a-distance” is a measure, which indicatesthe lateral displacement between the centers of the two distributorrows, whereas the “b-distance” indicates the height difference betweenthe centers of the distributor rows.

Profile 4 essentially is an L-profile, which also has been developed tocomprise two circular portions and which in a cross-section is designedin such a way, that these circular segments constitute portions, whichtouch the two legs of the L-profile. The L-profile has a bottom surface70 and an angular surface 71, which in its upper part has areinforcement 72, which constitutes an extension of surface 71 andpreferably has an angle of 90°.

Reinforcement 72 extends at right angles from angular surface 71 and isalso then bent again downwards towards bottom surface 70. Reinforcement72 is finally transformed into a first concave circular segment 73 witha circumference of altogether 180°, which in its rear part, after 90°reaches angular surface 71, where the angular surface constituting thebottom of one of the three grooves 64, which have been formed oncircular segment 73. In the lower edge of circular segment 73 theprofile extends an additional distance, a surface 75, away from angularsurface 71 and in parallel with bottom surface 70. Depending on thediameter of distributor 3, which preferably is smaller, than what istrue for measurement “b” for the profile, the profile comprises also anoblique plane 76, which connects surface 75 with a second cylindrical,concave circular segment 74, which at its lower part is terminated witha groove 64, the bottom part of which constitutes a part of the totalbottom surface 70. Circular segment 73 is provided with three grooves 64with a 90° division, the center groove extending at right anglesoutwards from angular surface 71.

Second circular segment 74 comprises only two grooves 64, one of themextending at right angles outwards from bottom surface 70 and the secondgroove being displaced 90° and towards angular surface 71. The radius ofthe two circular segments 73 and 74 is chosen in such a way, that itwill interact with the outer diameter of distributors 3.

Profile 4 may of course be designed in a somewhat different way withinthe scope of the invention. Its main function is to fix distributors 3in suitable positions and also indirectly in relation to cabinet 7,since the profile preferably will be fastened to cabinet 7 with screwsin a suitable way.

The profile also provides a high degree of motion regarding the mountingof the distributors and then also other components. Since the profile iscompletely open in its end portions, it is easy to replace thedistributors, because they do not have to be screwed or in other ways belocked in an axial direction.

FIG. 6 shows schematically, how a functional component 5 is designed.

This component may e.g. be a stop valve, a deaeration valve or a controlvalve.

FIG. 6 shows a simple check valve 66 with a measuring nipple 67. Thesedetails are not described exhaustively, because they just constituteexamples of components, which can be used in the complete installationunit 1.

FIG. 7 shows, how a functional component 5 is connected to distributor 3and to the load side.

From installation unit 1 a number of loops or tubes 32, connected inparallel, extend outwards to radiators or convectors or similar energydevices and the return from these loops 33 is connected to returnconnection 34 of functional component 5 by means of e.g. a pipe coupling35. According to FIG. 7 distributor 3 is in this case provided with twocut-offs 30 and thus to these two cut-offs two functional components areconnected. Functional components are in this case a standardized variantof a temperature-guided check valve 66 with mounted directly actingadjusting devices 69. Also, in this case the functional component isprovided with a measuring nipple 67.

The described design of the functional component must only be regardedas one example of the construction of the complete installation unit 1.
